Bangkok , Thailand -LRB- CNN -RRB- -- Thailand 's prime minister huddled with the chiefs of the country 's armed forces early Friday after a string of grenade attacks killed at least one person and wounded dozens of others in the already-tense capital .

Prime Minister Abhisit Vejjajiva called an emergency meeting of top officials after the Thursday night attacks , which followed weeks of protests aimed at toppling his administration .

Deputy Prime Minister Suthep Thaugsuban told CNN the grenades were launched from the area where the anti-government protesters , known as the Red Shirts , have been encamped for weeks , but the protesters denied any responsibility for the attacks .

Suthep told Thai television earlier that three people died in the attacks , but Bangkok 's Erawan Emergency and Rescue Center later revised the number to one . At least 87 people were wounded , the center said .

Suthep said riot police and helicopters were deployed to join Thai troops in the area , which was still littered with glass amid the standoff .

Across the barricades , the Red Shirts were playing music and trying to encourage a festive atmosphere .

Demonstrators told CNN late Thursday they wanted to drive home the point that their demonstrations are supposed to be peaceful .

Thursday 's explosions took place near an elevated train station where the Red Shirts are gathered , said Col. Sansern Kaewkumnerd , spokesman for the Center for Resolutions under Emergency Situation .

Three of the grenades landed on the roof of the station , but at least one landed outside a nearby hotel , Sansern said .

The emergency center , which records patients admitted to Bangkok hospitals , said the victims suffered wounds ranging from light to some more serious injuries .

Watch red shirt protests

The Red Shirts support former Prime Minister Thaksin Shinawatra , who was ousted in a bloodless military coup in 2006 . They want Abhisit to dissolve the government , hold new elections and leave the country .

Meanwhile , pro-government demonstrators in multicolored shirts have also mobilized to support Abhisit during the crisis .

Thailand 's military on Monday stationed about 1,500 troops in the area , a Bangkok financial center that houses offices for some of the nation 's largest companies . The Red Shirts are occupying a large area nearby . Clashes between the two sides left about two dozen people dead and hundreds wounded on April 10 .

Abhisit declared a state of emergency April 7 , hours after anti-government demonstrators stormed the country 's parliament . He said then that the `` purpose is to restore peace and order and to stop the spreading of false information to the Thai public . ''

Amid the long-simmering dispute , Thailand 's independent election commission recommended the dissolution of Abhisit 's Democrat Party after finding it accepted an $ 8 million campaign donation from a private company and mishandled funds allocated to it by the commission .

The ruling still must be reviewed by the country 's attorney general 's office and its Constitution Court , but if it stands , the 64-year-old party will be broken up , and Abhisit and its other senior leaders will be banned from politics for five years .
